Title: Circuit arrangement for bit error correction
Inventor: BRILL PETER
IPC: H04L25/04
Filed: 1981-07-08
Abstract: By means of the circuit arrangement for bit error correction which is described in the application, errors are eliminated which may occur in the transmission via a transmission channel of the binary sampling values, referred to here as transmission bits, of repeatedly sampled data bits. The central component of the arrangement is a bidirectional counter (5) which is timed by the clock (2) of the transmission channel. The transmission bits are sent to the bidirectional counting input (6) of the counter (5). The binary state of the most significant counting stage of the counter (5) is checked with a flip-flop (11) at the end of each data bit. The result of this check is sent to the Q-output (12) of the flip-flop (11) and represents the error-corrected data bit value which is obtained on the basis of a majority decision from all the associated transmission bits. <IMAGE>

Title: Cardan coupling
Inventor: SOTIROV IVAN DIPL ING
IPC: F16D3/30
Filed: 1981-08-25
Abstract: Cardan coupling in the form of a spherical linkage for the transmission of synchronous rotation between two shafts, with all joint and shaft axes intersecting at a centre in order to allow all the joints to be designed as radial bearings for the transmission of maximum loads, having the following elements: plane of symmetry which bisects the shaft angle and an axis of symmetry which lies perpendicular to the plane of symmetry and passes through the centre, comprising at least two differential guides. Each differential guide has the following principal components: two end joints connected to the two shaft ends in mirror symmetry with one of the elements, in one of the embodiments with the element forming the axis of symmetry, and a central joint which lies on the axis of symmetry, on the same operating reference circle as the end joints and is connected via connecting parts with all the central and/or intermediate joints, which rotate in and around the axis of symmetry at invariable spacings, and connects all the differential guides, none of the end joint axes of any of the differential guides coinciding. One differential guide can form a double-Z chain (see Fig. 14). It can also be a radial double universal joint combined with a Z chain, the centre of which is connected via connecting parts to the intermediate joints of the double universal joint. <IMAGE>
Patent DE-3134618-A1 (DE)
Title: Foot for steel tube support
Inventor: KOPAL RAINER
IPC: E04G25/00
Filed: 1981-09-01
Abstract: The invention discloses a foot for steel tube supports which is used in shuttering construction. The foot has at least three extensible struts, of which each one is articulated, by its upper end, on a sleeve, axially displaceably seated on the steel tube support, and, in the extended position, is supported against the lower end of the steel tube support via a further sleeve. The struts are in each case supported against the sleeve provided at the lower end of the steel tube support by means of an individually adjustable stiffening element, with the result that, irrespectively of the underlying surface on which it rests, the steel tube support can always be precisely adjusted into the vertical position by each individual strut being adjusted correspondingly. The foot may also be subsequently fitted on already existing, commercially available steel tube supports. Since it has two sleeves which are to be fixedly clamped on the steel tube support and on which the struts and/or stiffening elements are articulated, the struts can absorb some of the loading acting on the steel tube support, as a result of which the buckling length of the support is reduced. <IMAGE>

Title: Device for determining the degree of tanning (browning) of human skin
Inventor: SCHWEERS KARL H
IPC: A61N5/00
Filed: 1981-09-19
Abstract: A device is described for determining the degree of tanning of human skin, which consists of a light source of specific spectral composition and luminosity, by means of which the skin area to be investigated can be illuminated by light radiation, which is defined with respect to colour tone (hue) and light intensity, and of a light sensor for measuring the light reflected from the illuminated skin area. Such a device is suitable both for scientific and for medical purposes. However, the device can also be greatly simplified if the insistence on dedicated illuminating devices is dropped, and the human eye is used in conjunction with a comparative scale as "light sensor". The device becomes so economically priced as a result of this that it can also be used as an advertising medium.

Title: Appliance for admixing gas or aerating and/or circulating of, or generating flows in, liquids
Inventor: LIND HELGA
IPC: B01F3/04
Filed: 1982-03-05
Abstract: The invention relates to an appliance for admixing gas or aerating and/or circulating of, or generating flows in, liquids or liquids with solids, in which appliance according to the proposal of the main application, the flow is generated by at least one propeller mounted on the free end, immersed in the liquid, of a shaft, and the gas is introduced under pressure into the propeller zone, without a causal connection with the drive of the shaft. This appliance was further improved by means of the gas injection being possible, optionally, in two different ways, firstly through a duct which is arranged along an aerator housing surrounding the shaft and debouches in the propeller zone, and secondly via a connecting orifice, which can be opened and closed as required, off this duct with the interior of the aerator housing and via gas or air inlet orifices in the shaft fashioned as a tubular shaft through said tubular shaft. It has been possible to improve further the gas or air injection and the action at depth of the appliance, and the appliance can be adapted even more effectively to the particular requirement. By arranging the gas or air feed duct along the aerator casing and arranging the low-pressure compressor, which supplies this duct with gas or air, at the aerator casing end section which projects from the liquid, the appliance is provided with a compact, easy to handle, and manoeuvrable design. By virtue of the separate drive for generating the flow and for injecting the gas, this appliance, too, can be used both for nitrification and for denitrification in sewage plants (water treatment plants, biological purification plants). <IMAGE>

Title: Process for electrodepositing an alloy coating on a metal object, in particular a zinc/nickel alloy coating on steel strip
Inventor: ELZER RICHARD ING GRAD
IPC: C25D5/36
Filed: 1982-03-16
Abstract: In the process for electrodepositing an alloy coating on a metal object, in particular a zinc/nickel alloy coating on steel strip, the electrodeposition of the alloy coating is preceded by an intense electroless pretreatment of the metal object with the electrolyte in order first to deposit a zinc/nickel-containing thin primary layer so that the actual electrolytic zinc/nickel coating takes place on said primary layer. So that the alloy coating is deposited with a desired constant percentage composition, use is made of separate anodes which each contain only one alloy element and which are connected to separate electrical circuits in order to control the current at the anodes containing different alloy elements separately.

Title: Cable remote control with motor-driven tripod, only for video cameras
Inventor: HERRMANN BERND
IPC: H04N5/232
Filed: 1982-03-26
Abstract: There have long been tripods for cameras of any type, but the invention is a motor-driven tripod for rotating, lowering and raising, only for video cameras. The video camera always had to be operated by hand until now, that is to say one had to stand behind it so that it was not possible to become involved in the action itself. The cable remote control now makes it possible for everyone to operate and admire the entire action oneself from the easy chair. The video camera VK-800 E converted by me, the switches built into the handle of the video camera, pause-on-off for recording, focusing, telephoto lens, wide-angle lens. The advantage also consists in being able to follow the subject to be recorded on the TV screen.
